Hi,
It's my first experience with this.
I've extracted the *.m2v and *.ac3 files from a DVD with video clips.
So far so good.
I import them to Scenarist 2.7 and all works ok!
But... DVD Decrypter says that the *.ac3 files needs a delay of: -75ms.
Where inside Scenarist should I apply this number.
When I play the video in H mode, seems in synch.
Thanks

Can you hear 75 ms?

No I can't.
But it's my first aproach to this technique and I don't know if it's very important.
When I've used the m2v and the ac3 files on Scenarist, I have no complains from the soft.
-75ms or -24ms is a VERYYYYYYY little diference,
but why DVD Decrypter tells us to apply the diference?
Where can I apply that values ?

Yes, you can hear it. You'll notice lip sync problems.
I don't use scenarist - I use muxman (see link in my signature), where you can input the delay right on the main screen.

Since Scenarist has not an option for applying the delay time provided by DVDDecrypter, I've found a soft called "ac3 Delay Corrector" that applys the value and generates another ac3 file.
As far as I can see, it's enought for me.
Thank you all for the help.

Decrypter often gives wrong values for delays - check the delay with pgcdemux or vobedit. Decrypter calculates delay from decoding order - not from display order.
Scenarist has an option for negative delays
in track editor mark audio and edit the "start time" in the "property browser"
(note: "Start time to video" is for pos. delays and "Start time" for neg. delays, edit in fps, 1 frame PAL is 40 ms, 1 frame NTSC is ~33ms)

Thanks Bigotti5,
Can you give me the links for the PGCDEMUX and VOBEDIT ?
On DOOM9, the link for VobEdit 0.6 is broken.
